FIELD: designs of gas turbine engines.
SUBSTANCE: combustion chamber of gas turbine engine includes outer and inner housings, flame tube in air cavity between them and inlet diffuser with normalized break of air flow having perforated radial-cone wall. The last is formed as one piece with outer ring of diffuser and inclined to flame tube. Peripheral annular rib of said wall is mounted on inner annular rib of outer housing with possibility of their mutual axial motion. Wall has perforated openings of variable diameter. Relation of maximum diameter of opening to minimum diameter of opening is in range 1.5 - 2.5.
EFFECT: enhanced operational efficiency of combustion chamber due to elimination of thermal stresses between its outer housing and outer ring of diffuser, uniform pressure field at inlet of flame tube.
